FINAL ENVIRONMENTAL STATEMENT DEBRIS REMOVAL, NORTH BRANCH CHICAGO RIVER, ILLINOIS Prepared by U. S.

Draft (X) Final Environmental Statement Responsible Office: Army Engineer District, Chicago, Illinois 1. Name of Action; (X) Administrative ( ) Legislative 2. Description of Action: Clearing a 12-mile reach of the North Branch of the Chicago River, Cook County, Illinois cf fallen trees, roots, ensnarle- ments and unnatural objects. All debris and other assorted refuse within the channel lines would be removed to approved disposal areas provided by a local cooperating agency. 3a. Environmental Impacts; This stream bed improvement will remove conditions which contribute to flooding, unsightliness and pollution of the river. The proposed actions would not however eliminate major sources of stream pollution or make a significant contribution toward ameliorating existing water quality or flooding. 3b Adverse Environmental Effects; Limited areas may be disturbed by debris removal operations. A. Alternatives: "No action"; other combinations of scales of removal operations; methods of transporting accumulated debris and refuse to transfer points, and location and methods of final disposal; or the commitment of resources instead to a comprehensive and intensive effort for restoration of the entire river system to ecological health. 5 Comments Received: Environmental Protection Agency United States Department of Interior United States Department of Agriculture Soil Concervation Service United States Department of Transportation U.

Project Description. The proposed improvement provides for clearing the channel of the North Branch of the Chicago River, Illinois of fallen trees, roots and other debris and objects which contribute to flooding, unsightliness and pollution of the river. The North Branch Chicago River is located in the northwestern part of the city of Chicago, Niles and Morton Grove, Illinois. The reach to be cleared is approximately 12 miles long, between Golf Road in Morton Grove, Illinois, and the juncture of the North'Branch and the North Shore Channel just south of Foster Avenue in Chicago, Illinois. About 90 percent of the reach flows through Cook County Forest Preserve land. The project includes the complete removal of all debris from the river. Assorted refuse on the immediate bank area will also be removed. There will be selected removal of fallen and overhanging trees and branches. Clearing of debris from river will be accomplished by removing snags, logs, and branches from river to bank; felling and cutting large sized trees (fallen trees spanning the river and dead tree material); and removal of barrels, tires and other debris to shore. Debris to be removed includes visibly sunken, floating, or accumulated material on the immediate banks that impede flow at low water or that will likely in the near future cause ensnarlments. It was previously estimated that there was approximately 2,400 cu. yds. of debris to be removed. The work is scheduled to be accomplished during a three month period beginning during the latter part of the summer of 1972. The project has a $200,000 cost limitation. Removal of debris can be accomplished from highway bridges, adjacent golf courses and selected sites in the forest preserve system. More remote areas may be reached by temporary access roads, making use of natural acess areas adjacent to the river wherever possible. A survey will be required to delineate access points as well as the metes and bounds of the area to be cleared. The debris will be removed to approved private disposal areas. There are four private disposal areas within approximately 30 miles of the project area. Selection of a specific area or areas is the decision of the contractor awarded the job. No open burning of combustible material will be allowed. Performance of the above removal Is also the basic responsibility of the contractor. Clearing of debris however, will most likely be accomplished by manually removing snags, logs, branches from river to bank, felling and cutting large sized tree material, and winching of barrels, tanks and larger items to shore. This material will be transported by track equipment to a central collection point, or floated to a highway bridge. Trucks could then be loaded by truck mounted cranes or end loaders. If rafts are used to transport debris.temporary low water dams could be constructed of sandbags at highway bridge locations to facilitate debris removal in shallower isolated areas. Temporary dams could raise the water approximately 3 feet in each reach and permit flat-bottom skiff or rafts to float debris to highway bridges for loading into trucks. This stream clean-up project is considered desirable because of the improvement to environmental quality that will result. It will improve the general appearance of the area and enhance existing recreational use in the parklands. It may allow the river to flow somewhat faster and result in a minor improvement of water quality via flushing action. It will not, however, eliminate outfall'sources of pollution which are major detrimental factors to water quality. Finally it may alsp reduce flooding somewhat by removal of material which impedes the river's flow. 2. Environmental Setting Without the Project The North Branch Chicago River lie3 in densely populated portions of Lake and Cook Counties, Illinois. Its narrow and gently rolling plain is subject to flooding mainly in non- residential areas. Portions of urban land have been flooded in the past, and a substantially greater area is within reach of potentially greater floods. The river parallels the shoreline of Lake Michigan flowing with gentle slopes from north to south through residential, agricultural lands, forest preserve, parks, golf courses, and marshy areas. The average slope of the North Branch is about two and one-half feet per mile. Most of the stream course is through wooded areas, such as forest preserves and the overbank, or flood flows, are slugglish. The important tributaries of the North Branch Chicago River are the West and Middle Forks and the Skokie River. In the project area, the North Branch Chicago River flows through the Forest Preserves of Cook County, parkland of the city of Chicago, and some- private ownerships. The forest preserve districts, the primary purveyers of regional open space in Northeastern Illinois.have a tradition of low intensity development of their holdings. Forest preserves are therefor valuable remnants of natural areas for the enjoyment of the Chicago metropolitan area. Enabling legislation authorizes forest preserves to organize for the purpose of protecting and preserving the flora, fauna and scenic beauties within such district, and to restore, restock, protect and preserve the natural forests and said lands together with their flora and fauna, as nearly as nay be in their natural state and condition, for the purpose of the education, pleasure and recreation of the public. The river in project reach meanders through the communities of Morton Grove, Niles, and the City of Chicago. The width of the channel varies from 5 to 50 feet from bank to bank. The flood plain extends
